Further, the telescopic movement of the sliding nut 70 drives the first cross bar 24 and the second cross bar 25 to approach or separate from each other, so that the plurality of first baffles 21 and the plurality of second baffles 22 realize the lifting movement on the surface of one side of the base plate 10.

Preferably, in order to ensure smooth ascending and descending of the blocking plate 20, the first rail 24 and the second rail 25 are suspended on the surface of the one side of the base plate 10 to be close to but not in contact with the surface of the one side of the base plate 10.

The invention also provides a detection structure capable of avoiding damage to the parking spot ground lock 100 caused by malicious collision.

As shown in fig. 1 to 4, 12 and 13, the detection structure includes a strain gauge 13, the strain gauge 13 is disposed on the bottom plate 10, the strain gauge 13 is electrically connected to a driving motor 31 of the driving mechanism 30, when the strain gauge 13 senses deformation of the bottom plate 10, a signal is output to the driving motor 31, the driving motor 31 is started, and the driving transmission mechanism drives the blocking plate 20 to descend to an initial position. In the initial position, the stop plate 20 is at the lowest position, and the vehicle can freely enter and exit the parking space.

The strain gauge 13 is used for detecting the deformation of the bottom plate 10, so that the stop plate 20 can automatically descend, a vehicle can conveniently pass through the stop plate, and the problem that the vehicle lock 100 is damaged due to vehicle collision can be solved.

In a preferred embodiment, the base plate 10 includes opposite first and second sides 11 and 12, and the first side 11 is provided with a strain gauge 13; a gasket is arranged on the second side surface 12; wherein, the strain gauge 13 is used for sensing the deformation of the bottom plate 10; the spacer protrudes from the second side 12 so that a gap exists between the base plate 10 and the floor of the parking space, and the gap is used for providing a deformation space for the base plate 10.

The strain gauge 13 is disposed on the first side 11 and faces the blocking plate 20, and is helpful for directly sensing deformation of the base plate 10 caused by external force impacting the blocking plate 20.

The number of pads is, for example, 4, and 4 pads are provided at four corners on the second side of the base plate 10.

In a preferred embodiment, the strain gauge 13 is made of an elastic material, preferably a low carbon steel material, i.e. a low carbon steel strain gauge, which should not be too rigid to ensure a sufficient level of elasticity.

In a preferred embodiment, the first side 11 of the base plate 10 is provided with a groove 15, and the strain gauge 13 is embedded in the groove 15. The grooves 15 allow the thickness of the base plate 10 to be reduced, and thus, deformation of the base plate 10 caused by an external force is more easily sensed.

In a preferred embodiment, the number of the strain gauges 13 may be multiple, and a plurality of strain gauges 13 are disposed at corners and/or central areas of the first side 11 of the base plate 10, for example.

In a preferred embodiment, the strain gauge 13 is electrically connected to the driving mechanism 30, for example, the strain gauge 13 is electrically connected to the driving motor 31 through a wire.

In this embodiment, when the strain gauge 13 senses the deformation of the bottom plate 10, it is determined that the parking space lock 100 is impacted by an external force, and the driving motor 31 in the driving mechanism 30 is controlled to start according to the deformation condition, so that the blocking plate 20 moves downward and returns to the initial position.

The deformation condition of the bottom plate 10 is detected through the strain gauge 13, the stop plate 20 of the parking space ground lock 100 is driven to descend and reset, and the passing safety of a vehicle can be improved.

In addition, when the strain gauge 10 detects that the deformation of the bottom plate 10 occurs for multiple times within the preset time, or the strain example detected by the strain gauge 10 exceeds the preset pressure threshold, an alarm is output to prompt that malicious collision exists, and the malicious collision is interfered, so that the service life of the vehicle lock can be obviously prolonged.

In summary, the present invention provides a rotating structure and a parking space ground lock, wherein a receiving groove for receiving a ball is formed on a bracket, so that a screw rod as a rotating member directly contacts the ball, thereby replacing the existing ball bearing and reducing the friction resistance of the screw rod in rotation. Because need not to set up independent ball bearing, consequently for the volume of support reduces, and the whole volume of parking stall ground lock diminishes.
